Minyari Dome Project

Home » Minyari Dome Project

The Minyari Project covers 4,100km2 and features the Minyari Dome geological structure which hosts multiple delineated deposits

In May 2025, an updated Minyari Project Mineral Resource Estimate (MRE) was announced. The Minyari Project combined Mineral Resource now contains 2.5 million ounces of gold, 84,000 tonnes of copper, 666,000 ounces of silver and 13,000 tonnes of cobalt.

In October 2024, the Company announced the key outcomes of the Scoping Study Update completed on the Minyari Dome Development Project. The Scoping Study identifies a potential stand-alone gold mining and processing operation at Minyari Dome. It presented the preliminary evaluation of such a development at Minyari Dome based on the September 2024 MRE. Key highlights of the Scoping Study included:

  • Initial combined open pit and underground mine schedule of 30.2 Mt at 1.5 g/t gold for 1.5 Moz gold.
  • Over 10 years of initial processing life with a nameplate throughput of 3 Mtpa.
  • Simple, non-refractory metallurgy allows for a standard Carbon-in-Leach (CIL) process plant, delivering an estimated gold recovery of 90%.
  • Total pre-production capital cost of A$306M, including A$90M for pre-production mining.
  • Forecast average All-In-Sustaining-Cost (AISC) of A$1,721/oz (equivalent to US$1,205/oz).
  • Pre-tax NPV7 of A$834M and 52% IRR, assuming US$2,100/oz gold and 0.70 A$/US$ (A$3,000/oz).
  • Post-tax NPV7 of A$598M and 46% IRR, assuming US$2,100/oz gold and 0.70 A$/US$ (A$3,000/oz).
  • Pre-tax NPV7 of A$1,696M and 91% IRR, assuming US$2,800/oz gold and 0.70 A$/US$ (A$4,000/oz).
  • Post-tax NPV7 of A$1,205M and 79% IRR, assuming US$2,800/oz gold and 0.70 A$/US$ (A$4,000/oz).
  • Payback period of approximately 2.0 years from the commencement of gold production.
  • Latent potential to further boost economics with resource upside and by-product opportunities.

The Paterson Province geological setting of the Minyari Dome deposits is Proterozoic-aged, predominantly meta-sediment hosted intrusion related vein, breccia and replacement style precious and/or base metal mineralisation. Local controls on mineralisation commonly involve variations in both the competency/hardness and chemical composition of rock units, in combination with other “discrete” structural and intrusion controls.

At the Minyari deposit during 2021 mineralisation was discovered immediately east, west, and both up plunge to the southeast and down plunge to the northwest, including significant high‐grade breccia style gold-copper mineralisation.
